[Varieties of diphtheria: microbiological diagnosis and epidemiological observations (author's transl)].
Following several cases of diphtheria an epidemiological investigation was made in and around Aachen. A total of 1458 throat and nose smears were examined for various Corynebacteria species. Other than in two patients who had diphtheria, toxin-producing Corynebacterium diphtheriae was demonstrated in only one person who had been in immediate contact with them. Of a total of 150 Corynebacteria of different species which were isolated, two further isolates proved to be non-toxin-producing diphtheria bacteria. All five strains were found in foreigners, who represented 46.8% of all tested subjects. The number of isolated Corynebacteria of different species was, at 13.62%, almost double that in a group of non-foreigners (7.35%).
